“Be very careful, then, how you live — not as unwise but as wise, making the most of every opportunity, because the days are evil.” (Ephesians 5:15–16)
Lent invites us to examine how we live — not only spiritually, but practically. In a time of climate crisis, Paul’s call to “live wisely” speaks directly to how we use energy and transport. A Carbon Fast for the planet is one faithful way of making the most of this moment.
To live wisely today means recognizing that our daily choices — how we travel, how we power our homes, how much we consume — shape the future of God’s creation. Energy use is one of the largest contributors to carbon emissions. When we leave lights burning, overheat our homes, or rely heavily on fossil fuels, we unintentionally add to the suffering of vulnerable communities already facing droughts, floods, and rising food prices.
A Carbon Fast does not mean harsh deprivation. It means thoughtful change. It could include reducing car journeys and choosing to walk, cycle, or use public transport where possible. It might mean carpooling to church, working from home one day a week, or combining errands into a single trip. Each kilometre not driven reduces emissions and air pollution.
In our homes, we can switch off unused appliances, install energy-efficient lighting, lower geyser temperatures, line-dry clothes, or explore renewable energy options such as solar power. These actions save money as well as carbon.
Paul reminds us that “the days are evil” — not to instill fear, but urgency. Climate change is not a distant threat; it is a present reality. To fast from carbon is to refuse careless living. It is to align our habits with our prayers.
This Lent, may we choose wisdom. May our energy use reflect love for neighbour and reverence for God’s earth. And may our small daily decisions become acts of hope for the healing of creation.
