What is Greenhouse Gas and Why is it Important for your business?

GHGs are gases in the Earth’s atmosphere that trap heat. This heat comes from the sun, and some of it is naturally reflected back into space. Greenhouse gases, however, absorb some of this heat, which warms the planet. The main GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases.

The main sources of GHG emissions vary depending on the region, but globally, the biggest contributors are:

• Energy production: Burning fossil fuels like coal, oil, and natural gas for electricity and transportation releases significant amounts of CO2. Industry: Manufacturing processes often involve the release of various GHGs, including CO2, CH4, and N2O. Agriculture: Livestock farming generates methane through enteric fermentation, while rice cultivation releases methane from flooded paddies. Land use change: Deforestation and other land-use changes reduce the Earth’s natural capacity to absorb CO2.

The primary concern with rising GHG emissions is climate change. This includes:

• Rising global temperatures: This leads to more extreme weather events like heatwaves, droughts, floods, and wildfires.
• Sea level rise: Melting glaciers and thermal expansion of oceans contribute to rising sea levels, threatening coastal communities.
• Ocean acidification: Increased CO2 absorption by the oceans makes them more acidic, harming marine ecosystems. Changes in precipitation patterns: Altered weather patterns can disrupt agricultural production and water availability.

• Improving energy efficiency: Using less energy through equipment upgrades, behavioral changes, and renewable energy adoption.
• Switching to renewable energy sources: Replacing fossil fuels with solar, wind, geothermal, or hydropower. Reducing waste: Minimizing waste generation and exploring recycling and circular economy approaches.
• Sustainable sourcing: Partnering with suppliers committed to sustainable practices. Investing in carbon offset projects: Supporting projects that remove carbon dioxide from the atmosphere.

• The Paris Agreement: An international agreement aiming to limit global warming to well below 2°C, preferably to 1.5°C, compared to pre-industrial levels. (Focuses on national commitments)
• SEC Climate Disclosure Rule (US): Requires publicly traded companies in the US to disclose certain climate-related information, including GHG emissions.
• California Cap-and-Trade Program: A market-based program that limits greenhouse gas emissions from certain sectors in California.

• Use less energy: efficient appliances, turn off lights, adjust thermostats.
• Choose sustainable transport: public transport, cycling, walking, carpooling.
• Reduce consumption and waste: buy less, choose durable products, recycle/compost. Conserve water: shorter showers, fix leaks, water-efficient appliances.
• Eat less meat: animal agriculture contributes significantly to emissions. Support sustainable businesses.

Carbon footprint is a specific term that refers to the total amount of greenhouse gases (GHG) generated by an individual, organization, or product throughout its lifecycle. It’s typically expressed in terms of CO2 equivalent, as CO2 is the most abundant GHG. In simpler terms, GHG emissions is the broader concept encompassing all the different greenhouse gases emitted, while carbon footprint is a specific measurement of those emissions focused on CO2 equivalence.

Yes, there are a growing number of financial incentives to encourage businesses and individuals to reduce GHG emissions. These can include:

• Tax credits and rebates: Governments may offer tax breaks for companies investing in renewable energy or energy-efficient technologies. Individuals may also benefit from tax credits for purchasing electric vehicles or making energy-efficient home improvements.
• Green bonds: These are bonds issued by companies or governments to finance projects that have environmental benefits, like renewable energy or sustainable infrastructure.
• Carbon pricing initiatives: Some regions implement carbon pricing mechanisms, such as carbon taxes or cap-and-trade programs, which put a cost on carbon emissions. This incentivizes businesses to reduce emissions to avoid these costs.
