What You'll Learn
Fossil fuel companies are the biggest polluters
The largest corporate greenhouse gas emitter is Saudi Aramco, which has emitted almost 70 billion metric tons of carbon dioxide equivalent between 1965 and 2020. Chevron, ExxonMobil, Shell, and BP are also among the highest-emitting investor-owned companies. These companies have a huge role to play in driving climate change, yet they face an "absolute tension" between short-term profitability and the urgent need to reduce emissions.
While some fossil fuel companies have started to invest in renewable energy and carbon capture and storage projects, the sums involved and the pace of change are often criticized as being inadequate. International oil companies have been warned that they must completely change their business models or face a "nasty, brutish, and short" end within the next 10 years.
The continued expansion of polluting operations is made possible by the large profits these companies generate, which attracts significant investment. However, there has been some investor backlash, with several significant investment funds stating they will no longer support "dirty firms." The future may hold further backlash as consumers and investors become increasingly concerned about climate change, and fossil fuel companies risk wasting trillions by continuing to pursue worthless coal, oil, and gas projects.

Livestock production processes are the largest farm emission culprits
Businesses are the largest polluters, with just 100 companies responsible for 71% of global GHG emissions since 1988. Fossil fuel companies have been identified as the highest emitters, with ExxonMobil, Shell, BP, and Chevron among the top polluters. These companies have faced criticism for their environmental impact and have been urged to transition to renewable energy sources.
Livestock production processes are significant contributors to farm emissions, and efforts to reduce their environmental impact are crucial. Livestock farming accounts for an estimated 12% to 19.6% of global greenhouse gas emissions, with the regular digestive processes of ruminants such as cattle and sheep producing methane. Cattle burping, in particular, is responsible for over 90% of enteric methane emissions. Manure management systems, such as liquid manure lagoons, also contribute to methane and nitrous oxide emissions.
Feed production for livestock is another major emission source, releasing carbon dioxide and nitrous oxide. The manufacturing of fertilizers and other farm inputs, as well as the fertilization of crops, play a significant role in these emissions. Land use change, such as converting forests and grasslands into pasture or cropland, further exacerbates carbon dioxide emissions.
To address these issues, researchers are exploring strategies to enhance livestock productivity and reduce emissions. These include improving breeding, genetics, and nutrition, as well as implementing intensive rotational grazing systems to reduce nitrous oxide emissions. Additionally, dietary adjustments, such as low-protein diets for cattle, can help mitigate nitrous oxide emissions from manure storage, although there may be trade-offs with increased methane production.
The environmental impact of livestock production is a global concern, and reducing livestock emissions is crucial for mitigating climate change. By implementing sustainable practices and technologies, the industry can work towards minimizing its carbon hoofprint and contributing to a greener future.

Fashion industry produces 10% of our carbon footprint
Businesses are the largest polluters, with 100 companies responsible for 71% of global GHG emissions since 1988. The top 20 of these companies have contributed to 35% of all energy-related carbon dioxide and methane worldwide, totalling 480 billion tonnes of carbon dioxide equivalent since 1965. These companies continue to expand their operations, despite their devastating impact on the planet, as they are very profitable and attract a lot of investment.
The fashion industry, specifically, is the second-largest industrial polluter, producing 10% of global carbon emissions. This is a higher percentage than emissions from air travel. The industry releases 1.2 billion tonnes of carbon emissions every year, with the lifecycle of a garment, from manufacturing to transportation, and ultimately ending up in a landfill, contributing to this.
The pace of apparel manufacturing has accelerated consumption, with the average person today buying 60% more clothing than in 2000. Clothing production has also doubled in the first 15 years of the 21st century, with many European brands increasing the number of collections per year from 2 to 24. This has resulted in an increase in discarded items, fuelling overconsumption and overproduction.
The fashion industry's operating model exacerbates the problem, with the frequent replacement of clothing inventories and low-cost clothing stores offering new designs every week. Many clothing makers and consumers are calling for a more sustainable industry, with some suggesting changes such as switching to renewable energy in factories and reducing polyester use.
To decrease the industry's carbon footprint, individual and group action is needed to change the behaviours of big brands and consumers.

Multinational companies drive the climate emergency
Multinational companies play a significant role in driving the climate emergency. A small number of fossil fuel producers and their investors are responsible for a large proportion of global emissions. According to a report by The Carbon Majors Database, 100 companies have been the source of 71% of global greenhouse gas emissions since 1988. This highlights the critical role these companies play in tackling climate change.
The issue is further exacerbated by the profitability of these polluting companies, which continues to attract investments and enables them to expand their operations. Despite some investor backlash and efforts towards decarbonization, many of these companies still prioritize short-term gains over the urgent need to reduce emissions. They spend millions lobbying governments and presenting themselves as environmentally conscious while resisting significant changes to their business models.
The Paris Agreement has provided a framework for global decarbonization efforts, and some multinationals are taking steps towards climate action. For instance, companies like Ingersoll Rand, Mars, and BT are making progress in reducing their carbon emissions and investing in renewable energy solutions. These efforts are aligned with the goal of limiting global warming to 1.5°C and demonstrate the potential for businesses to drive innovation and growth while contributing to climate mitigation.
However, the current pace and scale of change are often insufficient to address the climate emergency effectively. Multinational enterprises (MNEs), due to their economic power and transnational reach, must play a pivotal role in the fight against climate change. They have the capacity to influence global value chains and make substantial emissions reductions through their decisions and actions.
To summarize, multinational companies have been significant drivers of the climate emergency, but they also possess the resources and influence to become key agents in mitigating its impacts. By prioritizing long-term sustainability over short-term profits and embracing innovative solutions, these companies can help lead the transition to a low-carbon future.

Businesses lobby governments to block climate change policies
Businesses have been identified as some of the largest contributors to global emissions. According to a report by The Carbon Majors Database, 100 companies have been responsible for 71% of global GHG emissions since 1998. The report also reveals that 32% of emissions come from public investor-owned companies.
Despite their significant impact on the planet, many of these companies continue to expand their operations, and some even lobby governments to block climate change policies. Oil and gas companies, in particular, have been accused of spending millions of dollars annually to weaken and oppose legislation aimed at fighting global warming. This has hindered governments' efforts to implement policies to meet climate targets and keep warming below 1.5°C, as outlined in the Paris Agreement.
A report by InfluenceMap claims that the world's biggest oil and gas companies spend $200 million every year on lobbying efforts. BP, Shell, ExxonMobil, Chevron, and Total are among the top spenders, with annual expenditures ranging from $29 million to $53 million. These companies engage in sophisticated efforts to influence politicians and the public on environmental policies, often presenting themselves as eco-friendly and committed to managing their emissions. They may also use social media to reframe the climate crisis and avoid addressing solutions.
While some businesses lobby against climate change policies, others advocate for pro-climate lobbying. Business leaders can lobby for pro-climate policies that align with their company's goals. For example, an automaker that produces electric vehicles could lobby the government to install EV charging stations. Additionally, businesses can join coalitions with other sectors or NGOs to lobby for climate action.
The tension between short-term profitability and the urgent need to reduce emissions presents a challenge for companies in driving climate change. However, investors play a crucial role in transitioning to a sustainable economy. By making their economic support conditional on companies' commitment to decarbonization, investors can influence companies to adopt more sustainable practices.
