Does caring for creation mean flying less? What does that mean for overseas missions?

This question matters because it sits at the intersection of two important Christian callings. On one hand, Jesus commands His followers to "make disciples of all nations" (Matthew 28:19). On the other, Scripture teaches that humanity is entrusted with caring for God's creation (Genesis 2:15). Some Christians wonder whether reducing air travel conflicts with global mission, while others worry that frequent flying undermines our responsibility to love our neighbours in a warming world.

The question also reflects an underlying assumption that Christians must choose between evangelism and environmental stewardship. Biblically, however, this is a false dilemma. God's mission has always been concerned with the flourishing of both people and the whole creation (Colossians 1:15–20; Romans 8:19–23). The challenge is not choosing one over the other, but discerning how to pursue both faithfully.

From a scientific perspective, aviation is one of the most carbon-intensive activities an individual can undertake. Commercial aviation accounts for roughly 2–3% of global carbon dioxide emissions, but when additional warming effects from emissions at cruising altitude are included, aviation contributes around 3.5–4% of human-caused warming. Unlike many other sectors, aviation remains difficult to decarbonise quickly because sustainable aviation fuels and zero-emission aircraft are still in development. Consequently, reducing unnecessary flights is widely recognised as one of the more effective ways that frequent flyers can reduce their climate impact. Climate change, in turn, disproportionately affects poorer communities through rising temperatures and sea levels, stronger storms, droughts, food insecurity, and displacement.

Scripture frames this issue through the lens of stewardship rather than prohibition. In Genesis 2:15, God entrusts humanity with creation:

"The LORD God took the man and put him in the garden of Eden to work it and keep it." (Genesis 2:15, ESV)

The Hebrew words imply both cultivating and protecting God's world. Christians therefore ought to consider whether our patterns of travel care for—or unnecessarily burden—the creation entrusted to us.

Likewise, Paul reminds believers that love looks beyond our own convenience:

"Let each of you look not only to his own interests, but also to the interests of others." (Philippians 2:4, ESV)

Because climate change most severely affects vulnerable populations who have contributed least to the problem, thoughtful decisions about our travel can also become an expression of love for our neighbours.

At the same time, Scripture clearly affirms the importance of crossing cultures to proclaim the gospel. Jesus commands:

"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." (Matthew 28:19, ESV)

The apostles travelled extensively across the Roman Empire to plant churches, encourage believers, and proclaim Christ. There is therefore no biblical basis for suggesting that Christians should cease international missions because of aviation emissions.

Instead, creation care invites the Church to ask better questions about how we travel. For example:

• Is this trip necessary, or could some meetings be conducted online?
• Could fewer trips be made, but for longer durations that deepen relationships and ministry?
• Are we partnering with and empowering local Christian leaders rather than creating dependency through frequent short-term visits?
• Could churches coordinate mission efforts to reduce duplicated travel?
• Are there opportunities to combine multiple ministry purposes into one journey?

These questions are not about guilt but about wisdom. They reflect the biblical principle that Christian freedom is exercised in love and service, not merely convenience.

For Singaporean Christians, this question has particular relevance. Singapore is an international aviation hub, and overseas ministry opportunities are unusually accessible. This is a tremendous blessing for the Church. Yet because international travel is relatively affordable and common, Singaporean Christians may also have greater opportunities to model thoughtful stewardship. Churches can continue supporting global missions while also considering alternatives such as strengthening long-term partnerships, investing more in local leadership, incorporating virtual mentoring where appropriate, and evaluating whether each flight genuinely advances God's kingdom.

Ultimately, caring for creation does not mean refusing to fly. Rather, it means recognising that every flight has environmental consequences and prayerfully considering whether those consequences are justified by the good being pursued. The Great Commission and creation care are not competing agendas. Both flow from loving the Creator, loving our neighbours, and participating in God's work of reconciling all things to Himself through Christ.
