Grilling season is here, and while picking the right grill can reduce emissions, what you choose to cook matters even more when aiming for a low-carbon summer barbecue.
- Food choices impact grilling emissions more than fuel type.
- Charcoal grilling has the highest carbon footprint among fuels.
- Electric grills’ emissions improve as power grids get greener.
What happened
Research from the University of Sheffield highlights that the largest source of greenhouse gases during summer barbecues comes from what is cooked rather than the fuel powering the grill. For example, a beef-heavy meal generates far more emissions compared to chicken or plant-based options. In fact, swapping beef for chicken can reduce a barbecue’s carbon footprint by about one third, while going fully plant-based can cut it by over half.
Besides the food itself, the fuel used also plays a role. Charcoal grilling, popular for its traditional flavor, carries a significant environmental cost because of both its production process and the emissions released when burning it. Manufacturing charcoal wastes much of the wood’s energy and releases substantial CO2. Burning charcoal for an hour can add more than 20 pounds of CO2 to the atmosphere, making it the most polluting grill fuel choice among commonly used options.
Why it feels good
Knowing that your choices at the grill can meaningfully lower your cookout’s carbon footprint offers a gratifying way to enjoy summer gatherings with care for the planet. Selecting leaner proteins or plant-based meals helps reduce environmental impact without sacrificing delicious flavors or convivial outdoor fun.
Additionally, moving away from charcoal toward cleaner fuels like propane, natural gas, or electricity—which benefit from an increasingly cleaner energy grid—lowers harmful emissions. These incremental changes in how you grill help support healthier air quality and reduce the impact on forests where charcoal production contributes to deforestation in some regions.
What to enjoy or watch next
Try experimenting with plant-forward barbecue recipes featuring vegetables, legumes, and poultry as your main grill stars this summer. Consider electric grills powered by renewable energy where possible for an even greener cooking experience. Recycling or repurposing your old grill is another step toward sustainability.
Keep an eye on innovations in sustainable grilling fuels and technologies that reduce environmental harm while delivering great taste. Whether exploring solar-powered grills or new pellet fuels, making conscious choices about summer cookouts can bring both enjoyment and peace of mind in protecting nature.
